The center of the heater 6 and the center of the stopper assembly 9 are located on the same vertical line, and the center of the adjustment cylinder 706 and the center of the storage platform 8 are located on the same vertical line to ensure that the stator will not deviate when the stator is pressed into the shell, thereby ensuring the quality of the finished product.

The heat insulating layer 10 can prevent the heated shell from damaging the limiting plate 905.

[0027] Specific implementation method: First, place the shell on the top of the placement rack 903. Due to the weight of the shell, the placement rack 903 will drive the slide 902 to slide downward along the surface of the slide rod 901 and squeeze the reset spring 907, thereby driving the several transmission rods 904 connected to the surface of the slide 902 to rotate, and then drive the limit plate 905 to move toward the shell along the guide groove 906 until it is close to the surface of the shell, so as to quickly fix the shells of different sizes on the top of the rotating table 2, and then the first cylinder 5 at the top of the first support frame 4 will drive the heater 6 to the shell below it. The shell body is heated by moving the first adjusting block 709, and then the rotating motor 3 drives the rotating table 2 connected thereto to rotate, so as to heat the rest of the shell body and transport the heated shell body to the bottom of the pressing assembly 7. The second cylinder 705 at the top of the moving seat 704 drives the adjusting cylinder 706 to move downward. After the adjusting cylinder 706 enters the shell body, the adjusting motor 708 starts and drives the threaded rod 707 connected thereto to rotate, thereby driving the first adjusting block 709 to descend. In this process, the first adjusting block 709 will squeeze a number of the second adjusting blocks 712, and then drive The clamping plate 711 connected to the guide rod 710 moves toward the inner wall of the stator and squeezes the clamping spring 713, so that the stator fixed by the limiting component 9 on the top of the storage table 8 can be clamped. Next, the second cylinder 705 will drive the stator to move upward. In this process, since the stator no longer squeezes the placement frame 903, the limiting plates 905 move in a direction away from the stator, thereby not hindering the upward movement of the stator. Then the moving motor 703 will start and drive the screw 702 connected to it to rotate, so that the moving seat 704 drives the stator along the second support frame 701. Move toward the top of the shell. When the stator moves to the top of the shell, the second cylinder 705 will drive the stator to move toward the inside of the shell. When the stator contacts the inner wall of the shell, the clamping plate 711 will squeeze the top of the stator, and the stator can be assembled into the shell. Compared with the original technology, the present invention can assemble shells and stators of different models, expanding the application scope of the device, and can install the stator into the shell while heating the shell, which not only greatly improves the assembly efficiency, but also avoids burns caused by manual assembly, which is beneficial to improving the safety of the equipment.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
